摘要：

The best results for the preparation of the oxide Bi1.42PbtSr1.8Ca2.2Cu2.85O10+v were obtained using Bi6Pb2O11 and very short sintering periods. Other precursor, Sr2-zNazCaCu2O5+x, led to good-quality single-crystals of Bi2-yTeySr2-zNazCaCu2O8+q (O < y < 0.3; O < z < 0.5). X-ray diffraction studies on these superconductors reveal small structural changes for different preparative conditions.
